MULTIPLE EXPLOSIVE-ENGINE.

Specificationv of Letters Patent.

Patented Dec. 8, 1908.

Application led November 1, 1907. Serial No. 400,228.

To all whom 'it may concern:

LBe itk known that I, ELMo HAMILTON WILLIAMS, midshi man United States Navy, and a; citizen of tfie United States, and stationed on the U. S. S. Nebraska, have invented certain newl and useful Improvements in Multiple Explosive-Engines; and I do hereby declare the fllowing to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which ,it -appertains to' make and use the f salme.

`My invention relates to improvements in ject of my invention is to producel a simple gas engine in which more than one explosion is reduced by each charge.-

y invention is applicable to two cycle, four cycle, or six cycle engines. i .With this object in View, my invention consists in the construction and combinations of parts as hereinafter described and claimed.I

Inthe accompanying drawingsFigure 1 1s thewcylinders thereof being shown partly in Fig. 2 is a plan view on the line 2---2V of Fig. 1, and Fig. 8 is a section of the engine cylinder showing. also the piston rod and driving crank with the means for operating the valves omitted.

In the drawing a two cylinder engine is shown,.but I do not restrict myself to the number of cylinders employed, as any desired number ma f be used.

o represents a 'ase plate secured by bolts l)v to anysuitable support. Made integral with, or attached to this base plate is the supporting frame c, on which are mounted twocylinders d and e. y

fis a casing surrounding said cylinders at some distance therefrom, leaving a place for the admission of water.

l Thecylinder d is of theordinary shape, but it haseither attached to, or made integral with it, an auxiliary casing g.

t represents the main compression space, and i re 'resents the secondary compression space. I hese are connected together by a port y', leading into the top'of the space 'i and ordinarily closed by the valve 7c mounted on fa valve rod Z, around which is coiled the spring m which normally holds said valve' c ose 'It represents ports leading from the cylinder into the space t.

multiple explosion gas engines, and the ob-` anend view of the complete engine, one of o represents the ily-wheel which is mounted on the shaft p, which shaft is provided with a crank g pivoted to the piston rod r which is pivoted to the piston s. s

t represents an igniter of any desired type.

u represents the inlet valve which ordinarily stops the passage o leading to the carbureter, and this valve is normal y closed by l the spring w coiled around the valve roda.

y represents a casing surrounding the top of the valve rod x, but this casing is not strictly necessary.

1 represents the valve which covers the eX- haust outlet 2. This valve is mounted upon a rod 3, and the sning 4 on said rod normally keeps the va ve closed. The valve '11, is opened by suction and the valves 7c and 1 by means which will now be described. On the shaft p is mounted a beveled gear wheel 5, which meshes with a similar gear wheel 6 on a short shaft 7, mounted in abearing 8 on the casing. The shaft 7 is also provided with another beveled gear wheel 9, which meshes with a similar wheel 10 on the shaft 11. This shaft is carried by a bearing 12 on the casing, and another bearing 13 on the Water jacket. This shaft is provided with a cam 14, which at the spring m and opening the valve The rod 11 is also provided with another cam 15, which acts upon a roller 16' upon the end of a lever 17, ivotcd on a bracket 1S on the top of the cy inder head, the other end ofsaid lever bearing against the end of the valve rod 3. It is obvious, however, that any desired means for opening the valves 7e and 1, at the proper time, may be employed.

The operation is as follows: Assuming the parts to be in the osition shown in Fig. 3, and the spaces or cliiambers t and i to be filled with a compressed charge, the charge in vthe chamber 7L is ignited in the ordinary Way, and the resulting explosion drives the pist 'in s down. As soon as the piston uncovers the upper parts of the orts n, as shown by the dotted line 19 in 4ig. 3, the charge in the proper time operates upon the end of the rod Z, compressing the chamber i is ignited and a second explosion occurs, driving the piston downwardfwith additional force. It should be noted that the first eX lesion occurs when the. parts are nearly int e position shown in full lines in Fig. 3, and that the second explosion occurs when the parts are in the position shownin dotted lines in said igure. Obviously at the time of the second explosion there will be a more effective leverage on the crank q than at the first ex lesion.

The piston aving been driven down to its lowest point of travel, the valves 1 and it' are opened by the cams 14 and l5, and the burned gases are then driven out through the eX- haust passage 2. On the next downward stroke a charge is sucked in through the passage v, the valve u yielding to permit this, and the entire space above the iston including the chambers 7i and i is i led with this charge. On the upward stroke this charge is compressed both in the space 7L and the space i, for as soonas the ports 'n are closed,

by the piston s the valve 7c is opened so that there is.a free communication betweenthe spaces 7i and fi, with the result that the charge is compressed to an equal degree in each of these spaces. When the parts reach the position shown in Fig. 3, the valve 7c is closed, the explosion occurs and the whole cycle is repeated. The operation in the cyllinders d and e is precisely the same but differentlytimed, as usual.

While I have thus described my invention,

wish it to be distinctly understood that I do not limit myself to the eX'act details shown and described, as niany changes might be made that depart from the spirit of my invention. For example, any desiredfmeans of ignition could be lused 'and any'desii'ed means or' operating the valves.' l
